由于Surpac软件本身功能的限制,基于Surpac块体模型的三维数值建模技术在处理复杂矿山地质形体时存在费时、繁琐等缺陷。通过沿用八叉树层层细分的基本思路,研究了多个地质形体的网格批量自动划分技术,针对现有计算机处理能力在解析精度与模型尺度方面存在的矛盾,借用多重网格法概念探讨了网格局部加密和多尺度划分问题。并应用VC++开发了三维数值网格划分自动化软件平台,使复杂矿山地质形体的计算网格划分更加便捷高效,为开挖力学状态数值分析的自动化提供有力支持。该系统在玲珑金矿原始地应力反演数值建模中得到了实际应用,结果表明,该方法是实际可行和有效的。
Due to the limitations of Surpac software itself, the three-dimensional numerical modeling based on the Surpac block model has some shortcomings, such as time-consuming and cumbersome processing. By following the basic idea of subdivision of octree layers, this paper studies the automatic grid batch partitioning technology for multiple geological bodies. In view of the contradiction between existing computer processing ability in terms of resolution accuracy and model scale, the concept of multiple grid method This paper discusses the problem of partial grid encryption and multi-scale partitioning. And the application of VC ++ has developed a three-dimensional numerical meshing automation software platform that makes the computational meshing of complex mine geology more convenient and efficient, and provides strong support for the automation of numerical analysis of excavation mechanics state. The system has been applied in the numerical modeling of the original stress inversion of Linglong gold deposit. The results show that this method is practicable and effective.
